@node Mail
@unnumbered Mail

Each feed item is converted to following MIME-complaint mail message:

@verbatim
From: "Feed's title" <feeder@localhost>
Date: Item's updated/published date, now otherwise
Subject: Item's subject
Content-Type: text/html; charset=utf-8
[X-URL: link presented in the item] (maybe multiple)
[X-Enclosure: enclosure link presented in the item] (maybe multiple)
[X-Author: author's name] (maybe multiple)
[X-Categories: item's comma separated categories]

Base64-encoded item's content. That is HTML as a rule.
@end verbatim

Each message is placed under @code{HEX(SHA512/2(title+content))} filename.
Unfortunately many feeds do not provide any date information at all.
Often multiple entries contain the same date. So you can not solely
depend on update/publish date.

@code{mtime} is properly set for each newly created mail message. Also
it is set to feed's update/published date for @file{new/} and
@file{cur/} subdirectories.
